multiple arrays through awk...

i am v new to awk, well unix as a whole really but im enjoying it alot...

im trying to extract some data from a file, and parsing it into arrays, ive trawled for hours on the internet and cant find much when it comes to awk and arrays??

anyway, heres the file:

tableA tableB tableC
1 1 3
2 3 2
3 2 1

tableD tableE tableF
4 4 6
5 6 5
6 3 4

i want to loop through this data, putting the array/array index name as tableA, B, C etc, and then have the numbers as elements of the each array, my long term hope is to pipe these out to a file, where they can perform some kind of sql statement, something like UPDATE tableA where field = '1';

so its essential i can reference the table names at a later stage, these will need piping out too.

its tricky, but ill get the hang of it!

thanks in advance. hopefully i can learn something here and apply it in future.

thanks again.

ARRAY_REPLACE(3)							 1							  ARRAY_REPLACE(3)

array_replace - Replaces elements from passed arrays into the first array

SYNOPSIS
array array_replace (array $array1, array $array2, [array $...]) DESCRIPTION
array_replace(3) replaces the values of $array1 with values having the same keys in each of the following arrays. If a key from the first array exists in the second array, its value will be replaced by the value from the second array. If the key exists in the second array, and not the first, it will be created in the first array. If a key only exists in the first array, it will be left as is. If several arrays are passed for replacement, they will be processed in order, the later arrays overwriting the previous values. array_replace(3) is not recursive : it will replace values in the first array by whatever type is in the second array. PARAMETERS
o $array1 - The array in which elements are replaced. o $array2 - The array from which elements will be extracted. o $... - More arrays from which elements will be extracted. Values from later arrays overwrite the previous values. RETURN VALUES
Returns an array, or NULL if an error occurs. EXAMPLES
Example #1 array_replace(3) example <?php $base = array("orange", "banana", "apple", "raspberry"); $replacements = array(0 => "pineapple", 4 => "cherry"); $replacements2 = array(0 => "grape"); $basket = array_replace($base, $replacements, $replacements2); print_r($basket); ?> The above example will output: Array ( [0] => grape [1] => banana [2] => apple [3] => raspberry [4] => cherry ) SEE ALSO
